[question] TypeError: SvelteRangeSliderPips is not a constructor

[lpoupet]

Describe the bug
Testing a svelte component that include RangeSlider does not works. I have an error :
TypeError: SvelteRangeSliderPips is not a constructor.

I'm testing a "classic" implementation with :

<script>
  import RangeSlider from "svelte-range-slider-pips";
</script>

<RangeSlider values={[50]} pips />

If I try to fork project and implement some tests with jest and testing library, I don't manage to make it works. Getting error :
Unrecognized option 'sourcemap'.

To Reproduce
Just try to test RangeSlider component in a svelte app.
For the second problem, you can fork : https://github.com/lpoupet/svelte-range-slider-pips

Steps to reproduce the behavior:
Run npm run test

Expected behavior
No error

hi @lpoupet

I don't quite follow what you mean by "classic". Are you meaning that you simply trying to import into a Svelte project? And if so, Svelte 2 or Svelte 3, or SvelteKit ?

Anyway, I cannot replicate, see; https://stackblitz.com/edit/vitejs-vite-4gezgs?file=src%2FApp.svelte&terminal=dev for example.
Please can you produce a reduced test case for me?

Secondly, I'm not sure what your issue is with sourcemap, but I think it's unrelated to this component and is an issue with the way you're loading Svelte. as sourcemap is a Svelte option, not a RangeSlider option. (https://svelte.dev/docs#compile-time-svelte-compile)

Hello,

The issue is, when we use the testing-library with a component importing the svelte-range-slider-pips

<script>
    import RangeSlider from 'svelte-range-slider-pips';
</script>

We have an error TypeError: RangeSlider is not a constructor.

The workaround is specify the /src path on the import

<script>
    import RangeSlider from 'svelte-range-slider-pips/src';
</script>

Because the testing-library will target the main path on the package.json.
